Career Enlisted Aviator (CEA) Fundamentals Block 5 Practice Test

Weight can be thought of as acting at a single point along the airplane’s longitudinal axis—the balance point where all the weight’s moments sum to zero. This is the point at which the aircraft would balance if it were supported there, and it dictates how the aircraft behaves in flight. The location of this balance point, the center of gravity, affects stability and control: a forward CG makes the aircraft more statically stable but reduces elevator authority, while an aft CG makes it less stable but easier to pitch and maneuver. The CG shifts as fuel is burned and payload changes, so it must stay within specified forward and aft limits for safe handling. The other options describe different concepts (wingtip location relates to roll stability, center of thrust to propulsion, tail cone is just a component) and do not define the weight balance point of the aircraft.
